TT back up camera help

Here is what I did with my back up camera. I mounted it just below the rear center clearance light and wired it to the light. Ran the wires through the hole for the clearance light to the transmitter. Drilled a hole through the paneling to the inside and mounted transmitter inside the cabinet that was there. I also wired the screen to the parking lights in the truck. So all that I have to do so get a picture is turn on the parking lights. Also works for passing or getting on the interstate, as I turn it on and I can see what is behind the trailer.
I also put a switch on the screen in the truck, so if I use the truck at night, I can turn he screen off.
